That hole allows access to the parking brake mechanism located inside the hub on the rear wheels.

If I have the same hole in mine, I never noticed it.

The access hole for the parking brake adjuster is only in the rear rotors, and it's in the wheel mounting face, not on the outside of the "hat" section like the one in the photo; have no idea what that hole would be for in a front rotor.
